Sion Ult and Ally Azir wall [GAMEPLAY]

I've been aware of this for a while and I kept thinking that you guys would pick up on it, but I haven't seen anything yet. Basically what happens, is when you ult with Sion and you attempt to go through an ally Azir wall, your ult will collide with it. It's really annoying and it's an interaction I don't think should be there. I can understand if it was an enemy Azir wall but you can just walk through ally Azir walls no problem, it should allow your ultimate to go through. I really hope this gets fixed.
